'Opposing' in the Bible

So when Peter went up to Jerusalem, those of the circumcision [certain Jewish believers who followed the Law] took issue with him [for violating Jewish customs],

But since the Jews kept resisting and opposing him, and blaspheming [God], he shook out his robe and said to them, “Your blood (damnation) be on your own heads! I am innocent of it. From now on I will go to the Gentiles.”
